Multiple Video Cards

post #1 of 3
Thread Starter 
Hey all, well I have been having a problem for a while worked on it worked on it some more then chose to ignore it. I have 2 video cards I work with three monitors.

The two cards are -
Geforce 7900 GSX (PCIE)
Geforce 5600 (PCI)

I used to run a 6600GT which worked seemlessley with the 5600. well it stopped working so i got a new card. The drivers apparently don't use the UDA, so i had to mess with it for a while. Well now for the past month or so the three moniros have been working fine except for some reason OPen GL doesn't like it. It says that "NVIDIA display driver files from different (incompatable) versions of the driver has been detected. NVIDIA open GL acceleration has been disabled in order to maintain system stability.

ODD, i never had this problem, a driver update would be what I am expecting to get as a response but i know that isn't the probelm , for if i update the driver the 5600 will prlly just die...... I remember it taking a long time to get this working the way it is just because windows doesn't like having two different drivers. Do any of you know of a way to tell stupid open GL to just use the 7900 and pretend like the old card doesn't exist.

BTW, Direct X works fine no problems at all there.


Any ideas would be a big help....

I have a friend doing the same thing except that both his card on PCI Express x 16. Maybe it's the fact that both your video cards are on different interfaces, and it causes problems whatsoever to run 2 different video cards on one computer. I know that Nvidia should make their drivers more unified UDA, so all cards can work together but it's not really the case right now. My basic advice would be to uninstall the previous drivers completly:

1-Go to http://www.drivercleaner.net/professional.php and download by clicking the small download symbol at the bottom.

2-Uninstall the display drivers from control panel and restart you computer

3-Once restarted, use the program you just installed and select Nvidia in the list, selecting Nvidia will only remove the display drivers (not your chipsets...) and restart your PC.

4-Install the latest Nvidia driver that just came out: http://www.nvidia.com/object/winxp_2k_93.71.html IF YOU ARE RUNNING WINDOWS XP.

But I'm pretty sure it's the fact that your cards are on different interfaces. Was your previous 6600 GT was on PCI or PCI-E? Or my other thought is that I think that both cards have different OPEN GL versions, so you are mixing different technologies and that would explain the problems. But if I were you, I would remove your old video card has it could slow down your PC.

Yes the other card was running on PCIE with the old crappy PCI card running one monitor...... don't notice a difference in 3 rendering or anything since i only use the 7900 for gaming etc anyway. If i remote the drivers the one card will just stop I already tried what you are mentioning but i will try it again..... I guess.
